Being flawed and human, we all make mistakes from time to time. Part of being human is making mistakes, learning from them, and growing as a person. It's perfectly okay to make mistakes or to stumble and fall. The important takeaway from mistakes is that we acknowledge them, learn from them, and use that gained knowledge to better ourselves. Remember, there's nothing wrong with making a mistake sometimes; but, we should do our best to improve ourselves through them.
Your progress might seem small; it might be exponential. But, the important thing is that you're making progress. You're putting in the time and effort to better your life, no matter what form that improvement might take. Always remember that you're doing great and progressing at a pace that suits you.
